• Number two on the brain-game shortlist (docs/brain-game-roadmap.md)
  • Nothing is scored on finding the number; everything is scored on the share of possibilities each guess killed
  • The bar visibly shrinks each turn. Guess 3 out of 1–100 and you watch it kill 3%
  • The end screen sets what you spent beside what halving would have cost — a comparison, not a mark
  • Four ranges: 1–50, 1–100, 1–500, 1–1000
  • It cannot be failed: run past the budget and it simply says how it went. The hint gives the current middle
  • A yes/no mode: narrowing a set of objects by property rather than a number by sizeplanned

✓ = done · ☐ = planned. Every game is built one step at a time like this.
